最短的函数
// 语言字串，除了可以获取对应语言外，还可以设置字串变量。可以是!var, @var或 %var，%var就添加元素外层。@var会过滤HTML，!var会原样输出HTML，%var会添加span外层。t('my name is @name', array('@name' => 'willam')); // 一个链接 l('User Edit', 'user/1/edit');
判断首页
drupal_is_front_page();
GLOBALS
$GLOBALS['base_url'] // URL root
GLOBAL 文档

得到ROOT目录
getcwd()DRUPAL_ROOT把URI(public://)地址转换为绝对地址drupal_realpath('public://xxx.csv'); // 得到系统路径file_create_url('public://xxx.csv'); // 得到URL
加载脚本&CSS
drupal_add_js('misc/collapse.js');drupal_add_js('misc/collapse.js', 'file');drupal_add_js(drupal_get_path('module', 'content_glider').

激活behaviors
Drupal.attachBehaviors(document);
加载jquery ui
drupal_add_library('system', 'ui.tabs');
查某个URL得到程序所在
SELECT * FROM dp_menu_router where path='admin/config/search/path/patterns'
查实现某个HOOK的所有函数
dpm(module_implements('menu'));使用drush: drush hook menu跳转
drupal_goto('node/1');drupal_goto(current_path());drupal_not_found(); // 跳转到404页面drupal_goto('<front>', array(), 301); // 301跳转
URI
URI to URL: file_create_url('public://js/gmap_markers.js');临时目录URI： temporary://URL
arg(1); // 提取URL第2个参数，例如node/1，会提取1$_GET['q']; // 得到当前URL路径 url('node/1'); // 网站相对地址 url('node/1', array('absolute' => true)); // 绝对地址 url('<front>', array('query' => 'action=do', 'fragment' => 'top'));
得到URL alias
drupal_lookup_path('alias',"node/".$node->nid);drupal_get_path_alias("node/".$node->nid);
路径匹配
drupal_match_path($_GET['q'], 'node/*');
图片
image_style_url('image_style_name', $node->field_image[LANGUAGE_NONE][0]['uri']); // 缩略图片URL file_create_url($node->field_image[LANGUAGE_NONE][0]['uri']); // 原始图片URL // 显示缩略图片 $variables = array( 'style_name' => 'image_style_name', 'path' => $node->field_image[LANGUAGE_NONE][0]['uri'], 'alt' => $node->title, 'title' => $node->title, ); print theme('image_style', $variables); // 显示原图 $variables = array( 'path' => 'path/to/img.jpg', 'alt' => 'Test alt', 'title' => 'Test title', 'width' => '50%', 'height' => '50%', 'attributes' => array('class' => 'some-img', 'id' => 'my-img'), ); $img = theme('image', $variables); // 带链接的图片 l(theme_image_style(array('path' => $variables['node']->field_logo['und']['0']['uri'], 'style_name' => '100x100')), 'node/' . $variables['node']->nid, array('html' => TRUE));
配置值存取
variable_getvariable_setvariable_del日期格式化
format_date($timestamp, $type = 'custom', $format = ''); date_default_timezone_set('PRC'); strtotime('-6-5 20:11');
返回JSON数据
echo drupal_json(array('xxx'));drupal_json_output(array('xxx')); drupal_exit();得到请求 arg(1); // 得到URI的第二个值
跳转 destination
任何表单，只要在URL上加?destination=xxx，提交后都会跳转到相应地址
url('xxx',array('query' => array('destination' => 'yyyy')) ); drupal_goto('user', array('query' => array('destination'=>'user/myorder'))); drupal_goto(drupal_get_destination());
自定义breadcrumb
$breadcrumb = array();$breadcrumb[] = l('Home', 'node'); $breadcrumb[] = l('Our Team', 'team'); $breadcrumb[] = drupal_get_title(); drupal_set_breadcrumb($breadcrumb);
Log
watchdog('event_type', 'name is :name', array(':name' => $name), WATCHDOG_WARNING);
文件操作
file_load($fid)->uri;file_move($file, 'public://xxx/');file_copy($file, 'public://xxx/'); file_delete($file); file_scan_directory('public://','/.*\.(png|gif|jpg|jpeg)$/'); // 扫描文件夹，返回file对象数组
Form API File upload
/node/1537950
entity edit form的form field element，以profile2为例
$form = array();field_attach_form('profile2', profile2_load_by_user($user, 'general'),$form, $form_state); // node field_attach_form('node', $node, $form, $form_state);
注意$form_state必须是form参数$form_state的原变量，clone的会报错。执行后会填充$form变量，可以附加到当前的form中。
如果想只提取部分的field，可以使用multiple_entity_form module。
node add form
$type = 'news';module_load_include('inc', 'node', 'node.pages'); $node = (object) array( 'uid' => $GLOBALS['user']->uid, 'name' => $GLOBALS['user']->name ?: '', 'type' => $type, 'language' => LANGUAGE_NONE, ); $form = drupal_get_form($type . '_node_form', $node);
还需要添加以下HOOK来处理AJAX时产生的错误
/*** Implementation of hook_form_node_form_alter().*/function mymodule_form_node_form_alter(&$form, &$form_state, $form_id){ //ensuring the ajax upload still has all the includes $files = (isset($form_state['build_info']['files'])) ? $form_state['build_info']['files'] : array(); $files[] = drupal_get_path('module', 'node') . '/node.pages.inc'; $form_state['build_info']['files'] = $files; }
得到element children
element可以互相嵌套，通过render可以把element转换为HTML，而render之前，element只是一个大型数组，一般的数组操作很难区分element部分，所以可以用element_children:
foreach (element_children($element) as $key) {$sub_element[]= $element[$key]; }
单实例
$static = &drupal_static(__FUNCTION__, array());
cache
$cache_key = md5(serialize($values));if($cached = cache_get($cache_key)) { $cache_data = $cached->data; } else { $cache_data = getData(); cache_set($cache_key, $cache_data); }
session
drupal_session_start();$_SESSION[$key] = $value;
修改用户名的HOOK
hook_username_alter();format_username($account); // 显示用户名
301 redirects
function mytheme_preprocess_html(&$variables, $hook){ if(!drupal_match_path(current_path(), '<front>') && !(user_access("administer users") || drupal_match_path(current_path(), "user\nuser/*"))) { if(module_exists('search404')) { search404_goto("<front>"); } else { drupal_goto('<front>', array(), 301); } } }
获取当前语言标识 (i18n)
$language = i18n_language_interface();$lang = $language->language;
生成用户的识别码
user_pass_rehash($account->pass, $timestamp, $account->login);
增删用户角色
$role_name = 'admin';$role = user_role_load_by_name($role_name);user_multiple_role_edit($uids, 'add_role', $role->rid); user_multiple_role_edit($uids, 'remove_role', $role->rid);
输出一个MENU（1 level）
theme('links', array('links' => menu_navigation_links('menu_name'),'attributes' => array( 'id' => 'footer-menu', 'class' => array('links', 'clearfix'), ), ) );
常用配置
当前主题：$conf['theme_default']网站名：$conf['site_name']
调试
dpm($vars);dpq($query);
